Cryptoschemes Based on New Signature Formation Mechanism

Authors: A.A.Moldovyan, D.N.Moldovyan, L.V.Gortinskaya

Abstract

Several variants of new digital signature schemes (DSS) based on the discrete logarithm and factorization problems have been proposed. Considered DSS are characterized in that a novel mechanism of the signature generation is used, in which two parameters of the (k,S) or (R,S) signature are defined after solving a system of two congruences. In the case of composite modulus additional restrictions conditions have been introduced for selection of the public key.
